I have tried some things, such as using the file .asoundrc and rebooting the pulseaudio daemon, but nothing is working.
This may have happened when I tried another Display Manager and reinstalled it back again because I was having problems. I think gdm3, not gdm, is installed, so I hope that is the right one.
Here are some important snippets on info that you may need:
